2. Fig. 1
Measurements of ACE activity in human SVs (n = 25), ITAs (n = 27), and old SVs (n = 16). Values are means ± standard error of the mean. **p < in the SV and old SV when compared with the ITA.

3. Fig. 2
Contractile effect of angiotensin II in isolated segments of SV (■, n = 18), ITA (●, n = 16), and old SV (▴, n = 9) bypass grafts. Values are means ± standard error of the mean. *p = in the SV when compared with the ITA and p = 0.03 in the SV compared with the old SV graft.

Contractile effect of angiotensin II in the absence (■, n = 6) and the presence of 10–4 mol/L l-NMMA (●, n = 6), 10–5 mol/L bosentan (▴, n = 6), or 10–6 mol/L indomethacin (☆, n = 6) in either (A) isolated segments of SV or (B) isolated segments of ITA. Values are means ± standard error of the mean.
